Parameters
- image
- Image to be resized.
- width
- New width of the image data.
- height
- New height of the image data.
- bitsPerPixel
- Output bits per pixel. Use 0 for 8-bit grayscale. Possible values are: 0, 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 24, 32, 48 and 64.
- order
- Output color order.
- ditheringMethod
- Flags that indicate the type of dithering, if bitsPerPixel is not the same as the source image.
- sizeFlags
- Flags that indicate the type of resizing.
- palette
- The palette to dither to if bitsPerPixel is less than or equal to 8. Pass a null reference (Nothing in Visual Basic) to dither to the fixed palette or if no palette is required.
Refer to RasterImageResize.
ditheringMethod is used when dithering is needed to produce the output bits per pixel. The interpolation usually requires that the input data be converted to 24-bit or 48-bit and then back to the desired bits per pixel. So some dithering might be required if the output bits/pixel are less than or equal to 8.
The Start method starts the resizing process. This will be followed by calls to ResizeBuffer to retrieve the resized data and by a call to Stop, to end the resize process and clean up any allocated resources.
